Architects have designed an "earth-scraper," a giant building that will burrow 300 meters (about 328 yards) beneath the city's main square, according to the U.K.'s Daily Mail. Shaped like an inverted pyramid, the design, by BNKR Arquitectura (pronounced "bunker," if we had to guess), is a creative response to the unique building challenges of densely populated Mexico City.
